A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 318 people over the age of55, 73 dream in black andwhite, and among 290 people under the age of25, 12 dream in black and white. Use a 0.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts b and c

b. Test the claim by constructing an appropriate confidence interval.

c. An explanation given for the results is that those over the age of 55 grew up exposed to media that was mostly displayed in black and white. Can these results be used to verify thatexplanation?
